Adapting Flange of Toilet Bowl

ABSTRACT

The present invention provides an adapting flange of toilet bowl typically including a main body having a through-hole at the center, and a sealing cap molded over the through-hole, wherein said sealing cap connects to the main body via a circular laminar connection portion, and a suspension link is attached on the top surface of the test cap. Due to the test cap integrated into the flange gasket as a whole body by the connection of the laminar connection portion, so the losing sealing cap will be efficiently avoided, it is convenient to be used greatly. Moreover, the laminar connection structure between the sealing cap and the main body, the sealing cap is easy to be tore off without any falling down into the drain pipe happened, due to the sealing cap torn-off along the laminar connection portion, the broken section left on the laminar connection portion is flat without toothed section so as to avoid hanging over the dirt to block the drain pipe happening, further to simplify the structure of the sealing cap, and to reduce the volume of the sealing cap and the manufacturing cost, meanwhile the flat broken open is left on the main body without toothed section so as to avoid hanging over the dirt to block the drain pipe happening.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an adapting flange, and moreparticularly to an adapting flange of toilet bowl.

2. Description of Prior Art

Before mounting a toilet on site, the drain pipe-line has to be checkedout to be sure whether the leak tightness of the drain pipe-line isgood, and the drain pipe-line is free or not. The common examiningmethod is that a flange gasket is mounted on the inlet of the drain pipefirstly, then sealing the mouth of the flange gasket with a test cap isto be used to seal the pipe-line for checking out, after examining, saidtest cap will be taken off and thrown away, finally by securing theoutlet of the toilet bowl on the mouth of the flange gasket exactly, thetoilet bowl is mounted on place. But in accordance with the most of theconventional products in the market so far, the test cap and the flangegasket are separated into two independent pieces, so that during thetransportation and store, or in the time of unpacking without mounting,said separated test cap is easy to be lost, in this time another sealingmethod has to be found out, or to buy another matching test cap,whatever some trouble will come out in the mounting process. On theother hand, for getting the leakage efficiency, besides securing thetest cap on the flange gasket, the other sealing mechanism has to beemployed so that the structure of the sealing cap is so complicated thatthe volume of the cap is increased relatively, and the manufacturingcost increases too, and the deserted test cap may cause waste ineconomic.

According to above-description, an integral plastic adapting flange witha molded cap came out, thereby avoiding losing. But, due to thestructure of the adapting flange, and the requirements of the injectionmolding processes, the connection portion of the sealing cap and themain body of the flange gasket is made so thick that it has to beknocked off with a hammer after examination, in the same time, theknocked fractions of the sealing cap will fall into the inside of thedrain pipe-line to cause blocking in the pipe-line easily. On the otherhand, after knocking off the sealing cap with the hammer, a toothedbroken open is remained on the flange gasket, so that after using thetoilet for some time, the toothed broken open will hang over with somedirt to cause blocking easily too.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide anadapting flange of toilet bowl, which facilitates to use with lowmanufacturing cost without any blocking caused after the examination inuse.

For achieving the above-mentioned object, the present invention providesan adapting flange of toilet bowl, which includes a main body having athrough-hole at the center, and a sealing cap molded over thethrough-hole, wherein said sealing cap connects to the main body via acircular laminar connection portion, and a suspension link is attachedon the top surface of the sealing cap.

Said laminar connection portion is molded round the rim of the sealingcap, and connected to the main body with the external edge by theinjection molding.

Said laminar connection portion is molded on the through-hole of themain body extending to connect the external rim of the sealing cap withthe internal edge by the injection molding.

As utilizing above-mentioned structure, due to the sealing capintegrated into the flange gasket as a whole body by the connection ofthe laminar connection portion, so the losing sealing cap will beefficiently avoided, meanwhile the through-hole of the main body issealed without any extra sealing mechanism attached any more, so thatthe drain pipe is sealed naturally and conveniently after the adaptingflange is mounted on. Additionally, because said sealing cap isconnected to the main body via a weaken laminar connection portion,after examining the drain pipe-line, just need to exert an extra forceon the sealing cap, the laminar connection portion will be torn away sothat the sealing cap is taken apart from the main body without anysecuring and sealing mechanisms attached on, further to simplify thestructure of the sealing cap, and to reduce the volume of the sealingcap and the manufacturing cost. Moreover, the laminar connectionstructure between the sealing cap and the main body, basing on theprinciple of levers, the test cap is easy to be rose at one side fortearing off without any falling down into the drain pipe happened, dueto the sealing cap torn-off along the laminar connection portion, thebroken section left on the laminar connection portion is flat withouttoothed section so as to avoid hanging over the dirt to block the drainpipe happening.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1 and FIG. 2, an adapting flange of toilet bowldisclosed by the present invention is used for attaching on the inlet ofthe drain pipe (not shown in drawings). Said adapting flange typicallyincludes a main body 1 having a through-hole 11 at the center, and asealing cap 2 molded over the through-hole 11, wherein said sealing cap2 connects to the main body 1 via a circular laminar connection portion3, and a suspension link 21 is attached on the top surface of thesealing cap 2.

In practicing, said adapting flange is attached on the inlet of thedrain pipe tightly (not shown in drawings), meanwhile said sealing cap 2molded on the main body 1 seals the inlet of the drain pipe naturallyand conveniently, facilitate to check out the drain pipe-line. Afterexamining the drain pipe-line, the user just needs to use a lever toolto rise the one side of the suspension link 21 up with one end, by meansof the weaken laminar connection portion, the sealing cap 2 will be tornoff along the laminar connection portion easily to take apart from themain body 1, then it is thrown away, after that, the toilet bowl can besit on place.
